aru4912 Posted July 6, 2007 Share Posted July 6, 2007 A drug that is highly effective in treating many types of infection can, at present, be obtained only from the bark of the ibora, a tree that is quite rare in the wild. It takes the bark of 5,000 trees to make one kilogram of the drug. It follows, therefore, that continued production of the drug must inevitably lead to the ibora’s extinction. Which of the following, if true, most seriously weakens the argument above? (A) The drug made from ibora bark is dispensed to doctors from a central authority. (B) The drug made from ibora bark is expensive to produce. © The leaves of the ibora are used in a number of medical products. (D) The ibora can be propagated from cuttings and grown under cultivation. (E) The ibora generally grows in largely inaccessible places. Folks, your inputs pls.

gmatnaive2 Posted July 6, 2007 Share Posted July 6, 2007 IMO E. The argument states that the trees will become extinct because 5000 needed to produce 1kg of drug. But if trees are inaccessible than they cannot be used. Will remain intact. Quote Link to comment Share on other sites More sharing options...
abhijit_s_2000 Posted July 6, 2007 Share Posted July 6, 2007 IMO E. If the Ibora tree is highly inaccessible places, it cannot be cut for the drug. Option D is wrong. Even if Ibora can be artificially cultivated, the rate of production of the drug will detroy the artificially cultivitated trees. Let me know if this helps.

kapil_leo Posted July 7, 2007 Share Posted July 7, 2007 It should be "D" If we can cultivate the tree it will never extinct. Quote Link to comment Share on other sites More sharing options...
humtum0 Posted July 16, 2007 Share Posted July 16, 2007 Agree with 'D' The issue here is "continued production of the drug must inevitably lead to the ibora’s extinction'...so in order to keep the drug flow continue and at the same time have the plant growth in tact we need some reason to suggest plant can be prosperd elsewhere to weaken the argument..That's what 'D' is suggesting. 'E' is not even focussing on real issue. Quote Link to comment Share on other sites More sharing options...
lawrencl Posted July 16, 2007 Share Posted July 16, 2007 A drug that is highly effective in treating many types of infection can, at present, be obtained only from the bark of the ibora, a tree that is quite rare in the wild.

Which of the following, if true, most seriously weakens the argument above? (A) The drug made from ibora bark is dispensed to doctors from a central authority. how the drug is dispensed doesn't help or hurt whether the tree becomes extinct (B) The drug made from ibora bark is expensive to produce. how expensive is out of scope © The leaves of the ibora are used in a number of medical products. using the leaves still doesn't prevent the tree from becoming extinct (D) The ibora can be propagated from cuttings and grown under cultivation. using the trees cut down can help grow more trees, sounds great to me (E) The ibora generally grows in largely inaccessible places. sounds like growing back the trees that were cut is going to be a pain IMO D Quote Link to comment Share on other sites More sharing options...
aru4912 Posted July 16, 2007 Author Share Posted July 16, 2007 I too opted for D but the OA is E. Quote Link to comment Share on other sites More sharing options...
mc007bond Posted July 16, 2007 Share Posted July 16, 2007 IMO D is this an OG question? i think the ans is incorrect Quote Link to comment Share on other sites More sharing options...
ken_english Posted July 22, 2007 Share Posted July 22, 2007 I think it should be D Quote Link to comment Share on other sites More sharing options...
DJValentino Posted August 21, 2007 Share Posted August 21, 2007 Agree with D. The reference answer is incorrect. Quote Link to comment Share on other sites More sharing options...
kikipooh Posted August 22, 2007 Share Posted August 22, 2007 I think D is the answer too. What is the source of this question? Quote Link to comment Share on other sites More sharing options...
LegoLife Posted August 22, 2007 Share Posted August 22, 2007 My answer is D. If the Ibora trees can be cultivated, then the trees will not become extinct. Hence, it weakens the conclusion. Quote Link to comment Share on other sites More sharing options...
username9 Posted August 22, 2007 Share Posted August 22, 2007 my choice is D but probably E becoz if it is inaccessible then it CANNOT BECOME extinct. thx \|/ Quote Link to comment Share on other sites More sharing options...
gmatrock Posted August 22, 2007 Share Posted August 22, 2007 OA is D pls check again Quote Link to comment Share on other sites More sharing options...
